FILLING on THREAD HOLDER FOR Looms;

Application filed .Tune 30, 1920. Serial No.

To all whom it may concern: I

Be it known that we, GRovER CLEVELAND HARALSON and WILLIAM ERNEST TURNER, citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Filling or Thread Holders for Looms; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to weaving looms.

and more particularly to an attachment therefor which will be hereinafter known as a filling clamp, the object of the invention being the provision of novel means for acting upon the filling at the time the latter, if properly laid, engages the usual filling fork so that the operation of the latter is rendered more accurate and effective.

In order that the filling shall tilt the fork, it is common to provide the lay with a rack or grate to support the filling in front of the fork as the lay heats up and sometimes this device has been reinforced by putting more tension on the filling in the shuttle. Both of these devices are objectionable, because lint 's liable to choke the grate and impair the proper action of the fork and owing to the closeness of the grate bars to each other, any looseness in the lay or the fork support will cause the tines of the fork to strike the grate and prevent the detecting action of the fork, while the increased tension of the fork on the shuttle causes the filling to pull too on the selvage when the shuttle is going across the lay.

It is one of the main objects of our invention to do away with this filling rack and provide suitable means which will effectively engage and retain the lay threads in a tight position after being drawn across the warp threads, thus reventing any slack in the lay threads, WlllCl causes loose weave in the cloth.

Another object of the present invention is the provision of a filling clamp for looms, adapted to be operated simultaneously with the movement of the lay, whereby the filling clamp head will automatically contact with the lay thread and clamp the same against the back of the shuttle box after the lay thread has been drawn across the warp Specification of Letters Patent.

threads and the shuttle is in its position within the box prior to returning across the warp threads, and upon the rearward move ment of the lay, the clamp will be automatically removed from contact with the lay thread and permit the shuttle to return to the oppositeside of the lay, the clamp being-operated through the movement of the With the above and other objects in view, the Invention consists in the combination and arrangement of parts hereinafter more fuly setforth, pointed out in the claims and shown in the accompanying drawings, in which- Fignre 1 is an end elevation of a weaving loom lllustrating'our improved filling clamp attached thereto, I Fig. '1 is a detailed front elevation showmg the relative positions of the clamprod and the filling brake,

Fig. 6 is another cross-section ofthe. clamping head, taken at right. angles to Fig. 5, and

Fig. 7 is a detailed sectional view taken on the line 7'7 of Fig. 1.

Referring now more particularly to the drawings, the numeral 1 indicates the frame work of a weaving loom and 2 the lay sup porting rod which is mounted for pivotal movement upon the frame as shown at 3. The lay rod supports the lay 4 and in the present illustration, we have illustrated that portion of the shuttle box as indicated at 5.

Secured to one of the horizontal portions of the frame 1 is a U-shaped clamping member 6, one end of which is bolted to the horizontal portion of the frame by means of the view taken head illustrating the bolt 7, said bolt extending through the frame Y 19 and this bolt handle member 11. This rod is the cus-' tomary operating Mounted for pivotal movement upon the other arm of the u-shaped bracket dis a block 12 provided with a suitable opening through which the fillingclampv rod 13 ex tends, said rod being retained in vertical adjusted position within this block 12 by means of the set screw 14. The lower end of the filling clamp rod 13 is connected to the lay supporting rods 2 by means of a clamping member15 which is formed of a single strip of fiat metal having its intermediate portion brought together to form an arm 16, having extensions at its outer end provided withfiarcuate pockets 17 adapted to embrace the rods ,2 and in order to retain the 17 into clamping engagement with the rods 2, the portions at 16 are clamped together by means" of a-bolt 18 provided with a nut 18 also clamps in position the pin 20. which is 'disposed'in the intermediate portion-of the strip as illustrated at 21'. Connected to the eye 22 of this pin 20 is a coil spring 23, the other'end of'said coil spring being connected by I pin 24: to the lower end of the filling clamp rod. 13. It will be noted that 'by connecting the rod 13 to spring 23 the same will be moved to an oblique position, clamping the thread 28 against the. layfranie upon the forward beat of the same. The'upper end of the filling rod 13 movable brake head 25.,having a pocket 26 formed in the face thereof, in which is arranged the clamp member 27, this clamp member 27 which clamps the lay thread 28 against the rear wall of the shuttle box is formed of felt, rubber; or any other suitable material and is yieldably mounted within the pocket 26 and providedwith a tension spring 29. In the present instance, the tension spring29 is formed of-the flat leaf type. i I

In Figs. 5 and 6, we have illustrated the brake head as provided ;with coil tension springs 30 disposed'within the pocket 26 and arranged between the clamp member v27 and the innerwall of the pocket 26 to provide suitable tension for the brake member 27 when it contacts theshuttle box;
